I had s_x on September 4th, and I was still on the pill. but i had to quit taking it like two days later because i didnt have the money to afford it. But I am on my period right now yet this morning I woke up feeling really good and a half hour later I was on my knees puking. And then afterwards I felt perfectly fine. I am just so confused and I would really like someone to help me understand if I may be pregnant.
